METHOD OF CONTROLLING COMPOSITION OF MULTICOMPONENT GASEOUS MEDIUM IN SEALED CONTAINER AND CONSTRUCTION OF SEALED CONTAINER Russian patent published in 2018 - IPC G01N7/14 G01N27/416 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of methods for regulating the parameters of gaseous media and can be used to control the concentration of gas components of the investigated gas media. In contrast to the known method of controlling the composition of a multicomponent gaseous medium in a sealed container, comprising a room emitting aggressive gaseous products of material to store it in the cavity of the container, carrying out in the container an element for introducing a passive medium, according to the invention, maintain a constant natural inflow into the cavity of the container of the passive medium in the form of oxygen with the air flow through a removable calibrated tubular as an element for introduction of a passive medium and real-time recording of the content of the aggressive gaseous component in the gas environment of the container is carried out by means of appropriate concentration sensors of the aggressive component, the content of which is changed to nominal with the use of a complex powdered absorber of oxidized products of interaction of the aggressive gaseous component with air oxygen, consisting of a powdery water scavenger and a powdered catalyst for the reaction of hydrogen binding to hydrogen hydroxide. Establishment of the fact of the safe content of the aggressive gaseous component in the gas environment of the container are performed by comparing the measured concentration of the aggressive component in a gaseous medium with a nominal value (safe).

EFFECT: technical result is the provision of safety and the possibility of more precise control of the concentration of an aggressive component of the gaseous medium with the maintenance of a nominal safe state, taking into account the change in the complex of indicators of a multicomponent gaseous medium.
